Angular Services

Angular services are a fundamental concept in Angular applications. They are singletons that are shared across components, allowing you to manage and share data and logic. In this section, we will explore some of the key Angular services.

Key Angular Services

• HttpService: Used for making HTTP requests to a server.
• Router: Manages navigation within the application.
• Location: Provides information about the current URL.
• EventEmitter: Used to emit events from a service to components.

Example Usage

Here's an example of how to use the HttpService to fetch data from a server:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class MyService {
  constructor(private http: HttpClient) {}

  fetchData() {
    return this.http.get('/api/data');
  }
}
